IMPROVEMENT IN MACHINES FOR SOLD-ERING CAN.CAPS.

Specification forming part of Letters Patent No. [09,577, dated A\'ovemlnr 20, 1F70.

To a/ZZ whom may concern.-

Be it known that I, WILLIAM B. Elsner, of Brooklyn, in the -county of Kings and State of New York, have invented a new and useful Improvement in Machines for Soldering Gan- Caps; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enableothers skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a side View of Iny improved machine, partly in section, to showthe construetion. Fig. 2 1s a horizontal section of the same, taken through the line x, Fig. l.

Similar letters of reference indicate corresponding parts.

My invention has Afor its object to furnish a Simple, eonvenienbrancl effective machine for soldering caps upon sheet-nietal cans; and it consists in the construction and combination of various parts of the machine, as hereinafter more fully described.

A. is the lower platform ot' the machine, which is securely attached to and supported by legs B, of such a length as to raise the machine toa convenient height.

C is the upper platform, which is connected to the platform A and supported by the rods D, which have screw-threads cut upon one or both ends to receive nuts, which are screwed upon the said rods, one above and one below each platform, as shown in Fig. 1. This construction enables the two platforms to be adjusted at a greaterv or less distance apart, ac-

cording to the height of the'eans to be soldered.

E is the furnace, in which the re is formed to heat the soldering-tool, and which vis provided with a detachable cover, and with openings to admit the air to support combustion and for the escape of the smoke and other products of combustion.

F is the heater, which is abar of cast-iro11.

or other suitable material, placed vertically in the center ofthe furnace E, with its lower end the rod H, which passes down throughthe heater F and soldering-tool G, so that its lower end rests upon the said cap. The upper' end of the rod H is weighted, to enable it to hold the' cap securely in place while being soldered.

I is the table,- upon which the can is set to be operated upon, where it is securedin place by the bar .J ,t which is curved to receive the can between its arms, where it is held by the elasticity of the said arms, the ends of s aid arms being curved outward slightly to allow the can to be conveniently forced into place between them. The middle part ofthe elastic or spring bar J is attached to the upper end of the support K, the lower end of which is se cured to the table I, near one edge, by ascrew, which passes through a slot in the lower end of the said support K and screws into the said table. I, as shown in Figs. 1 and 2, sothat the position of the said bar J maybe adjusted ac cording to the si ze ofthe can. rLhe table I is made circular in form, and is securely attached to the upper end of the vertical shaft L, which passes down through and revolves in the lower platform, A, and in a support, M, attached to said platform Ain such a way that the-said shaft may haveV a vertical movement through its bearings. rlhe lower end of the shaft L rests and revolves in a step pivoted to the end of the lever N, which is pivoted to a support attached to the platform A, andto the outer end of which is pivoted the upper endof the connecting-rod O, the lower end of which is pivoted to the treadle l?, the inner end of which is pivoted to the'lioor, or to some suitable support, an'd the outer end of which projects into such aposition that it may be conveniently reached `and operated by the operator with his foot to raise the can to the soldering-tool.

To the shaft L is attached abevel-gea-r wheel, Q, thev teeth of which mesh into the teeth of the bevel-gear wheel R, attached to the shaft S, which revolves -in bearings attached to the platform A, :ind to the end of which is attached a, crank, T, by means of which the vertical shaft L is revolved, the wheel Qbeing con-l necked with the 'shaft L in such a Way as to carrythe said shaft- L with it in its revolution,

While allowingthe shaft to have afree vertical movement.

If desired, several sets of 'tables and soldering-tools may be connected with the same crankshaft, so that a. number of can-caps'may 3. The combimbionof'fhe adjustable ensue holder J K with the revolving tablel', subst'zm-` tially as herein shown and described;- and for the purpose set forth.

4. An improved machine for soldering can- L caps,- formedvby the Combination' of t-he platform A, .feet B, adjust-able platformC, adjusting and supporting rods V1)furnace E, heater F, ring or cup sh aped soldering-tool Gr, weighted, holding-rod H, 'cable I,- adjustable holder K, shaft. L, lever N', 4treadle P, geur-wheels Q and E, shz'ifb' 4S, and crank T, with each other, substantially ashe'rein shown and described, and for lche purpose set forth.

4The above .specification of my invent-ion signed by me this 25th day of July, 1870.

`WILLIAM B. BISHOP.
